Let us not concentrate too much on the unknowns. I'd happily learn more about the knowns. With more knowns, we (those who are not already in a conspiracy of one) can perhaps work out whether that silence from the Fish is externally applied (from either Evil or non-Evil source...) or a personal choice of gambit.
The chances are that at least one of you did something last night, even if it was a mafia-action that you'll now have to lie about or else spin in a different light to look good. That I don't say that you definitely had actions should tell you something about me, but I need to feel better about where I stand before I tell more.
I of course flat-out deny that I'm the Evil one, as I expect everyone to. Thus consider doing as I've thought of doing, and couching what you say in flavour terms. Perhaps you think there's a connection to some role you can trust, even if you don't know the person it is? Inaction in the last game would have resulted in more drenchings (both types fatal to me, it seems!), and maybe I could have made those hints good enough for Fish to pick up on. I just hope it isn't Fish again that's the same partner.
I think you'll agree that this is necessary, in this scale of game. I can just sit here and play all day and all night, if necessary but it's useless if none of us know the score.
